i The main objects of this invention are: 7 First, to provide animproved typewriter desk or cabinet in which the typewriter is rigidlysupported when in" erected position.

' writer cabinet from which the typewriter may be withdrawn and swung toerected position which is easily, operated toqerect or -Secon d,'toprovide an improved. typeto 'col'lapsethe structure. I

.Objects pertaining to details and econoimies of'my inventionwilldefinitely appear from the detailed description to follow. efinedand p'oi-nt--' The invention is clearly ed out in the claims. V V v Astructure embodying the features of .myinvention is clearly illustratedin' the accompanying drawing forming a part of this application, inwhich:

i Fig. 1' is a front perspective view offa typewriter desk orcabinetembodying the features of w my invention with the desk closed.

Fig; 2 is -a fragmentary perspectiveview with the top of the deskremoved showing the mechanisms in collapsed positioni" F g. 3 1savertical section on a line corresponding to line 3 3 of Figs. 1, 2'and5 n 22 which are pivoted to the actuatinglev'ers with the parts incollapsed position;

Fig. 4 is a vertical section with the parts extended or erectedposition.

Fi .5 is a. fra 'mentar view art-l in g b horizontal section wlthcertain of the'parts shown in extended position by dotted lines.

Referring tothe drawing,the desk 1 is provided with acompartment'or;cabinet'2 adapted to receive a typewritingmachine. Withinthis compartment I mount slideways 3 which support the plate-like slides4, the details of the mounting of the slides upon the ways, however,not'being shown.

The typewriter bed 5 is mounted upon the slidesby means of a pair ofrear supporting posed rearwardly. The, rear links 6 are prolinks 6 and apair of front-supporting links 7, the links being. pivoted on the slidesat. 8 and 9, respectively, and, pivotally connected to the bed. .Thefront supporting links 7 arebent' or angled, their'angles being disvidedwith outwardly projecting stops 10 which are adapted toQswing int-othe'notches 11 in the slideswhen the parts are in erected position,thereby limiting the upward swing of the bed. i

The'movement of the slides is limited and controlled by the. 1inks'12which are pivoted at 13 to coact with stop pins l l'on the gagement withthe notches 15 in the links 12 on thefforward movement of the slides Thelinks 12- are supported laterally b {5 01,1 he Slides. I I 1 a links6,.the pins 14 being brought into en- 7 This arrangement allows thecarriage to be brought well forward before the lifting or elevatingmovement begins, adapting the mechanism'to a. wider carriage machine andpermitting it to raise without touching the top of the desk. I Asfthebed is raised the links engagein the pins of the'le'vers holding thecarriage from movingback duringthis elevating movement and at thesame-time 'holding the bed in proper position, the car riagehaving arearward movement as it raised instead of moving in a perfect arc.

The links also hold the carriage from being pushed back into the deskwhen the bed is in elevated position.

.A pair of actuating levers 17 is pivoted at 18; onthe front endsof theslides and connected by the 'links 19 to the actuating- '2 'springs'20,the springs'being connected at.

their rear ends to the cross piece- 21011 the to the supporting links 7by means of links.

slides. Theactuatin-g levers are connected connecting the links 1'9 tothe actuating levers "are arranged so that the. pivot 23 swings past'theline through thefpivots 18v ajnd24t when the parts are in 'erected'posntion, thus providing a locking toggle. The.

pivots'18 are extendedto provide stops'cos actin awith the links.22-limiting the "upward b movement of these parts.

One ofthe actuating levers isprovided with a handpiece 26by means ofwhich'the toggle may be broken. The toggles are operatively connected byan equalizingmeans comprising a pair of equalizer bars 27 which arepivoted at 28 on a cross piece29 extending between the slides.Tl1eseequalizer bars engage the lugs 30 on .thelinks 19 thereby connecting theparts and also supporting the links 19. A link 31 connects vtheinnerends of the equalizer bar;

With the'parts thus arranged springs of the required tension to lift thebulk of the load may be provided so that the structure is very easilyoperated, the movementof the parts being controlled by the hand piece sothat there is no material shock. The parts are secured inerectedposition by the locking toggle described so that the support is veryrigid and at the same time may be easily collapsed.

Ihave illustrated'and described my improvements in one embodiment whichI have found satisfactory. I have not attempted to illustrate ordescribe other embodiments or adaptations as it is believed that thisdisclosure will enable those skilled in the art to embody or adapt myimprovements as may be desired. 7
